Business, to be successful, must be based on science, for demand and supply are matters of mathematics, not guesswork.

But in my opinion, all things in nature occur mathematically.

Pray that success will not come any faster than you are able to endure it.

The line between failure and success is so fine. . . that we are often on the line and do not know it.

The integrals which we have obtained are not only general expressions which satisfy the differential equation, they represent in the most distinct manner the natural effect which is the object of the phenomenon... when this condition is fulfilled, the integral is, properly speaking, the equation of the phenomenon; it expresses clearly the character and progress of it, in the same manner as the finite equation of a line or curved surface makes known all the properties of those forms.
